The easy to read gallons … WebValve with limiter pilot and metal fittings. It limits the flow that circulates through the valve by means of a pressure difference between the valve and the limiter disk. When the dynamic pressure (due to the flow) exceeds the value of the pilot, this forces the passage in the valve to close, limiting the flow that circulates through it. Normally used in hydrants.
